Chapter 6 · The Twelve Houses
द्वादशभावविचाराध्यायः
क्रूरहतैश्शशिसूर्यादृष्टैर्ग्रहधातुतो मांद्यम् ॥षष्ठगृहस्थे खेटे तद्दोषेणैव रोगसंभूतिः ॥
The four may be struck by bad planets and not looked at by the Moon and Sun. Then illness comes from the dhatu (body tissue / state) of the planets. When a planet is in the 6th house, illness arises from that planet's own humour.
Simple meaning: The four struck by bad planets and not seen by Sun and Moon: illness. A planet in the 6th brings illness of its own humour.
चत्वारोप्यशुभहताश्चंद्रो दग्धो यदैकएषाञ्च ॥
The four struck by bad planets, the Moon burnt, and one of them in ithasala with the 8th lord: serious risk.
यदि निधनेशः क्रूरस्तद्दोषादन्तरेण बहुमृत्युः ॥
Bad 8th lord: great risk. If it is weak and in ithasala with a good planet, do not say so.
पूर्वोक्ताश्चत्वारो यदि षष्ठाधीशमुथशिलकृतास्स्युः ॥
The four in ithasala with the 6th lord: a longer illness; if the 6th lord moves fast, it ends soon.
